Cathedral in Blue

We passed by this cathedral (St. Nicholas Naval Cathedral) three or four times before we actually went on the grounds. I even took this photo though a fence because we were on our way elsewhere and didn't have time to explore it. But, when I saw it, I decided that I must paint a room or a house or something the same blue as is this cathedral. It's the prettiest blue I've ever seen.Still haven't painted anything, but I'm still young. I'll get to it.
